Title: Steel powder production method - using oxygen and argon gas atomising jet
IPC: C21C7/00
Filed: 1973-11-06
Abstract: Cast iron in molted state fills a crucible and is allowed to fall via an opening in the bottom, into the atomising chamber where a gas jet consisting of oxygen and argon under pressure, atomises the iron and blasts it against a plate suspended in the chamber while a laminar stream of water running down the plate rapidly cools the particles and carries them down into a collecting section of the chamber, where the slurry is carried via a pipe to a water separator after which the moist powder is carried to an intermediate holding tank from where a pipe or gutter directs the powder to a drying conveyor at the end of which the powder drops into a storage hopper. The method provides an economical way of producing steel powder.

Title: Absorption heat pump system for central heating - uses return flow of gas and liq. to drive ammonia mixture pump
IPC: F25B15/02
Filed: 1986-02-13
Abstract: The heat pump system has an absorbing unit in which ammonia vapour is absorbed in water under low pressure.

IPC: F16H55/06
Filed: 1998-08-20
Abstract: The main feature of the invention is the particular shape of the basic rack (poz). It consists of consecutive toothed profiles of the basic rack (pzoz). They consist of straight lines according to the equation: y = k.x, parabolas according to the equation y = m.a(1-(1-x/m)n) and arcs. This basic rack forms the teeth of straight toothed cylinder shaped gearwheels and the teeth of slant toothed cylinder shaped gearwheels with any number of teeth. While driven, such gearwheels feature a predominantly concave - convex fitting and improved geometric - kinematic properties regarding mutual sliding of surface sides. Such gearwheels also feature considerably better conditions for providing a lubricating oil strip as well as a smaller contact load of the teeth sides. Therefore such gearwheels are more resistant to defects of scoring, galling of sides, they are more resistant to grey spots, feature a better efficiency and improved strength at the root of the teeth.
